I've always been curious as to why you're not comfortable on a five. Not that I have anything against four-strings at all, but I was wondering if it's mostly a technique preference issue, like the lack of ability to wrap your thumb around the top. I've heard some say that a five-string neck is too wide, but other than for wrapping your thumb around the top, I've never seen how it could be percieved as too wide, as it's basically a four-string with an additional low string that you don't even have to play if you so choose. Basses with higher strings have the problem of stretching over the additional higher strings, but there is no extra stretch to the standard EADG on a fiver. It can be looked at and played exactly like a four IME, but I don't know how others feel. Opinions?
